@mUoM OJ: %mz/ To all whom it may concern:

Be it known that 1, ROBERT E. Krnsorr, a citizen" of the United States,andresident of lvlilwaukee, in the county of Milwaukee and State ofWisconsin, have invented certain new and useful Improvements inMultiple-Seat Units; and I do hereby declare that the following is afull, clear, and exact description thereof.

The present invention relates to new and useful improvements in seatstructures and is more particularly directed to the provi sion of astructure wherein a plurality of seat portions are combined in a singleunit, to thus reduce the essential number of sup porting legs, whereby astructure is provided which is relatively simple and which permits readycleaning therearound by means of a broom or the like.

It is in general the object of the present invention to simplify andotherwise improve the construction of structures of this character, andit is more particularly an object to provide such a structure which maybe very readily assembled to adapt it for use as a knock-clown orportable structure if so desired.

It is further an object to embody the foregoing features in a foldingseat structure wherein the assembled relation of various supportingparts holds the seats for proper pivotal movements.

WVith the above and other objects and advantages in view, the inventionresides more particularly in the novel combination, arrangement andformation of parts more particularly hereinafter described andparticularly pointed out in the appended claims.

In the drawings, Figure 1 is avertical transverse sectional view througha chair seat unit constructed in accordance with the present invention,this view being taken on the line 11 of Fig. 2; Fig. 2 is a frontelevational view of a seat unit, with parts broken away to more clearlydisclose the pivot mounting of the seats.

Referring now more particularly to th accompanying drawings, there isprovided a pair of end supports preferably comprising each a quadrantalframe 5 at the upper corner of which is provided a pair of spaced arms 5between which the body bar 6 of the seat unit is secured as by the bolts6, the bar seating onthe frame to relieve strain on the bolts. This bodybar is rectangular in cross-section and is formed in channel HSpecification of Letters Patent.

shape to provide a relatively large crosssection facilitating attachmentof the seat carrying bars-7- These bars are secured to the body bar byspaced depending arms 8 arms 8, bar 12 and brace 13 preferably comprisean integral structure.

The seats proper are preferably each formed of a plate 1a of materialbraced at its side edges by angle irons 15 and each seat proper ispivotally mounted between a respective pair of seat bars by pivot shafts16 which are loose in pivot openings 17 formed in the intermediate seatbar portions and which have reduced ends engaged in respective pivotopenings 18 of the single irons 15.

The pivot shafts are disposed in their respective pivot openings as theseat carrying bars 7 are assembled and are held against displacement bythe shoulders formed by their reduced ends. It is thus noted that thebolts 6 and 9 form the only means for holding the entire structureassembled, and thus a ready assembly and disassembly of the structuremay be had, to adapt it as a portable or knock-down structure if sodesired.

It is noted that the body bar 6 forms the forward support for the seatangle irons 15, and that the various strains incident to persons Weightson the seats are so distributed that strain on the securing bolts isobviated whereby they serve merely to hold various parts againstdisplacement, and thus a structure of maximum strength is procured.

I claim:

1. A seat structure comprising a body bar, members extending laterallyin spaced relation from said bar, back portions carried by said members,and seat portions pivotally carried by said members and adapted to reston the body bar.

2. A seat structure comprising a channeled body bar, members extending'later ally therefrom and including portions embracing and seating onsaid bar, and seat and back portions carried by said members.

3. A seat structure comprising a body bar, members extending laterallytherefrom and provided with pivot openings, seat portions provided attheir sides with pivot openings, pivot shafts disposed in the open- 10ings of the said members, and reduced extensions at the ends oftheshafts engaging V in the openings of the seat portions.

In testimony that I claim the foregoing I have hereunto set my hand atMilwaukee,
